Patented Apr. 2 6, 1932 UNITED STATES PATENT OFFICE PERCY L. DUNNAM, 011 FORT WORTH, TEXAS 1 F03 REMOVING BROKEN VEHICLE Axnns Application filed June 12, 1931.

an removal of one wheel and its associated axle invention residing in the constructon, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and where- Fignre 1 is a view of the tool partly in section.

Figure 2 is an enlarged section taken on the line 22 of Figure 1.

Figure 3 is a similar section taken on the line 3.3 of Figure 1.

Figure 1 is a section taken on line 4-4 of Figure 1.

The tool forming the subject matter of the present invention embodies a hollow tubular member of uniform diameter throughout its length, except at one end, where 1t is formed to provide a square opening, through which the clamping jaws slide. The opposlte end of the tubular member 10 has threadedly associated therewith, a cap 11 having a central opening to slidably receive the threaded section 12 of a shaft arranged within the member 10. The other section 13 of this shaft is provided with a longitudinal threaded bore 14 opening at one end thereof, to accommodate the threaded section 12 as illustrated. The section 12 is provided with a head 15 through which is passed a rod 16 constitutmg a handle.

Serial No. 543,989.

Manifestly by rotating the section 12 in one or the other direction, the section 13 of the shaft is caused to move longitudinally of the tubular member, and in order to limit this movement of the shaft, the section 13 is slotted as at 17, and receives the stop pin 18 terminally connected with the tubular mem ber 10 as shown.

The outer end of the shaft section 13 is recessed as at 19 to receive the clamping jaws 20. The jawsare preferably formed from a single piece of suitable material, folded upon itself, and attached to the shaft by means of a pin 21 passed between the jaws at the closedend thereof, and through the recess 19 of the shaft section 13. The corresponding free ends of the jaws are formed with inwardly directed gripping flanges 22.

In use of the tool for the purpose above mentioned, one wheel and its associated axle section is removed from the axle housing. The

tool is then inserted in said housing through the open end thereof, with the jaws open or spread apart. After the tool has been properly positioned within the axle housing, that is, with the jaws 20 straddling the adjacent end of the axle section to be removed, the handle 16 is operated to rotate the threaded section 12 of the shaft, to move the jaws 2O inwardly of the tubular member 10. During this operation, the jaws are moved toward each other into gripping relation with the axle section to be removed, causing a powerful grip 011 the latter, so it can be easily removed from the axle housing together with the tool. Obviously this duty can be readily and easily perfd'rmed, without the necessity of either entering the difierential housing, or otherwise interfering with the differential mechanism. The tool is simple in construction, can be manufactured and sold at a nominal cost, and is very easy to handle and manipulate for the purpose intended.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein illustrated or described, and that such changes may be resorted to when desired, as fall within the scope of what is claimed.

What I claim as new is:

1. A tool of the character described comprising a tubular member having a square opening at one end thereof, a shaft movable longitudinally within said member, a pair of normally open relatively movable jaws carried by one end of the shaft and slidable through the opening in the tubular member, means for operating said shaft 'to slide the jaws inwardly through said opening, whereby said jaws are moved into gripping relation, said shaft having a longitudinal slot, and a stop pin carried by said tubular member and passed through said slot, to limit the movement of said shaft in either direction.

2. A tool of the character described comprising a tubular member having a square opening at one end thereof, a shaft arranged in said member and including a slidable section and rotatable section, a pair of relatively movable jaws carried by one end of the slidable section and movable through the opening of said tubular membensaid slidable section having athreaded bore opening at its inner end, said rotatable section being threaded in said bore, and means for rotating the latter mentioned section to slide said jaws inwardly through said opening of the tubular member, whereby said jaws are moved into gripping relation, and means for limiting the sliding movement of said section in either direction.

In testimony whereof I aflix my signature.

PERCY L. DUNNAM.
